Title: Apparatus for performing a working sequence
IPC: G07C1/00
Filed: 1971-09-08
Abstract: 1419064 Teaching apparatus W R CLARKE 30 Nov 1972 [8 Sept 1971 (2)] 41822/71 and 55417/72 Divided out of 1419065 Headings G4T and G5G Apparatus for aiding an operator in the performance of a multi-stage task (e.g. for use in teaching the assembling of component parts and analysis of the trainee's performance) comprises means for successively presenting to the operator at a working station items necessary for carrying out each stage and, in synchronism therewith, information concerning the respective stage. The items may be presented by an indexable cylindrical container formed with a peripheral array of compartments. The information may be visually presented on a screen and/or audibly presented over headphones from a prerecorded tape. Indexing of the container and of the information presenting arrangement may be in response to the operator manually depressing an index button or a selected timed indexing-sequence programme. In setting up such a programme, the relative time intervals allowed for the individual stages and the overall speed of stage progression may be adjusted. Counters for indicating the time taken to complete the various stages may be provided. Lights may indicate how the times taken compare with target times for the various stages. At appropriate times, certain treated items may be made to glow by U.V. light to draw them to the operator's attention. When the apparatus provides working stations for two or more operators, indexing of items and information is not effected until all the operators' indexing buttons have been depressed. Components to be assembled may be of an exaggerated size during initial stages of training and may be progressively reduced in scale to the actual size. A similar reduction in the scale of the visually presented information may also be effected. Part of the apparatus may be for a tutor, whose performance of the task is relayed over closed circuit TV to the trainees. The trainee's stepping sequence is then determined by the tutor's. Trainee-monitoring facilities are provided for the tutor, who can selectively communicate with and control a particular trainee station whilst allowing the rest to continue under automatic or trainee-actuated sequence. The tutor can also arrange for the repeating of an individual stage of the task.

Filed: 1973-12-03
Abstract: 1444570 Semi-conductor switching circuits ALLIS-CHALMERS CORP 3 Dec 1973 [12 Dec 1972] 55982/73 Heading H3T [Also in Division H2] A control circuit for a D.C. load, preferably a series motor M, comprises a main silicon controlled rectifier SCR1 operated in a variable pulse width modulation manner to provide load currents over a range between high a low values, another rectifier SCR3 which is fired to cause a commutating capacitor C to turn off the rectifier SCR1, and a further rectifier SCR2 which is fired to reverse the capacitor voltage subsequent to charging through members M, L2 and SCR3 and prior to further firing of the latter to turn off rectifier SCR1, the latter operation being enhanced at high load currents by greater energy transfer from inductor L2 and the inductance of the battery source and supply lands to the capacitor C, which is thus charged to a voltage greater than that of the battery. At high currents this effect also serves to turn off the rectifier SCR3 through diode D. During operating conditions involving the turn on of rectifier SCR1 before the capacitor C has charged to the battery voltage, the rectifier SCR3 is turned off by discharge of the capacitor through rectifier SCR1 prior to its reversal of charge by firing of the rectifier SCR2.

Abstract: 1,103,179. Calendar timepieces. HAMILTON WATCH CO. Dec.15, 1966 [March 11, 1966], No. 56304/66. Heading G3T. A setting mechanism for a timepiece calendar ring 12 comprises rotatable pins 48, 50 for manually setting the position of the calendar ring and cam means 56, 58 for automatically returning the rotatable pins to a predetermined rest position. A setting stem 24 has a first position corresponding to the normal running of the timepiece, a second position for adjusting the calendar ring and a third position for setting the hands of the timepiece. In the second position a setting pinion 26 meshes with the teeth 28 of a wheel 30 which is attached to a wheel 40 by a staff 38. The wheel 40 meshes with a cam wheel 46 attached to which are the pins 48, 50 and the cam 56. Rotation of the stem 24 in its second position thus causes one of the pins to enter a slot 20 between the calendar ring teeth 18 and rotate the calendar ring. A cam follower 58 is loaded by a spring 62 so that when the setting stem is released, the end 64 of the follower urges the pins into a rest position away from the teeth 18. A detent 65 ensures correct location of the calendar ring after each adjustment. In a modification, Fig. 3 (not shown) the cam means is arranged so that each of the pins has a rest position in one of the slots 20 thus providing a self-locking mechanism for the calendar ring.

Title: Electric current regulators
IPC: G05F1/455
Filed: 1970-12-08
Abstract: 1336876 Automatic current and temperature control E OTT 8 Dec 1970 [2 Jan 1970] 58285/70 Heading G3R The R M S value of current through a load RA, which may comprise the heater of a protective housing associated with the measurement of fluid parameters, is maintained at a desired value by phase-angle control of a Triac T15 whose firing signal is dependent on a first signal representative of the arithmetic average value of the current and a second signal representative of a pre-set signal corresponding to the desired value, the latter signal being varied in dependence on the phase angle in each halfwave for which the current flows. Figure 2 shows the main components of the regulator in simplified form, the details of these and additional components also being described, Fig. 3 (not shown). The arithmetic average value of current is provided by a current transformer m feeding a resistor-diode bridge supplying an actual value signal through a resistor-capacitor network. The pre-set signal is obtained from a rectifier and voltage divider combination A, B whose output is passed, after combination with the modifying signal dependent on the phase angle of the current, to a differential amplifier E, H also receiving the actual value signal. The modifying signal is obtained from a resistorcapacitor-Zener diode circuit in which the capacitor voltage is a function of the phase angle. The amplifier E, H consists of a resistortransistor bridge E supplying an error signal to another differential amplifier circuit H via an RCR network providing a proportionalintegral regulating action. A zero-voltage switch I produces discharge of a capacitor during each zero crossing of the supply voltage, a Schmitt trigger K being triggered when the capacitor voltage reaches a predetermined value and causing a further capacitor to be charged to a predetermined voltage for discharge through an ignition stage L which fires the Triac T15. If it is desired to provide temperature control of the aforementioned protective housing, the temperature of the latter is sensed by a thermistor forming part of a Schmitt trigger M, which controls members I, K to cause current to be supplied when the temperature falls below a predetermined value. Switch I can be blocked by the member M to prevent firing of the Triac when the temperature is at its predetermined value.
